How to make your PC faster with cmd

Using Command Prompt, you can fix a slow PC by performing the following steps:

  1. Run “chkdsk” command to check for disk errors and fix them.
  2. Execute “sfc /scannow” to scan and repair system file integrity.
  3. Utilize “defrag” command to defragment the hard drive and optimize performance.

What is the command for chkdsk : chkdsk /f – Attempts to fix bugs or errors while scanning the hard drive. chkdsk /r – Attempts to fix sectors on the hard drive to make them readable in the file system. chkdsk /x – Disconnects a drive to scan and fix it. chkdsk /f /r /x – Scans the file system and its sectors, and fixes any errors found.

In the example above, DISM uses Windows Update to replace any corrupt files when the /Restorehealth switch is specified. Alternatively, you can prevent DISM accessing Windows Update by using the /LimitAccess switch.

Which is better, CHKDSK r or f : chkdsk /f fixes any structural issues with the file system and directory, correcting inconsistencies between the two. chkdsk /r searches for corrupted parts of the physical hard drive (while also running chkdsk /f) and tries to recover the data there to put it in a part of the drive that isn't damaged.

Is CHKDSK f safe : Is CHKDSK safe Yes. CHKDSK scans the hard drive for errors — such as the blue screen of death — and can help make your computer safer. However, the chkdsk /r command may delete data if it finds a bad sector, so ensure to do a backup before running it.
